Finding specific technical parts like the AN4U Wiyona Chan SM1612C can sometimes feel like searching for a needle in a haystack, especially when dealing with specialized electronics or niche manufacturing components.
While the string "AN4U Wiyona Chan" doesn't correspond to a widely known consumer brand, the model number SM1612C points toward a very specific category of electronic hardware: the Surface Mount (SMD) Crystal Oscillator.
Here is a deep dive into what this component is, why its specifications matter, and how to handle it in your projects.
Understanding the SM1612C: The Heartbeat of Modern Electronics
In the world of PCB (Printed Circuit Board) design, timing is everything. Whether you are building a simple microcontroller project or a complex wireless communication device, the system needs a "heartbeat" to synchronize operations. This is where the SM1612C comes into play. What is the SM1612C?
The SM1612C is a Quartz Crystal Unit housed in a miniature surface-mount package. The "1612" in the name refers to its physical dimensions: 1.6mm x 1.2mm. This ultra-small form factor is designed for modern, high-density electronics where space is at a premium. Key Technical Specifications
While individual manufacturers (like Wiyona Chan or others) may have slight variations, a standard SM1612C typically features: Frequency Range: Usually ranging from 24MHz to 54MHz. Load Capacitance: Common values include 8pF, 10pF, or 12pF.
Frequency Tolerance: Often ±10ppm or ±20ppm, ensuring high precision.
Operating Temperature: Generally rated for -40°C to +85°C, making it suitable for industrial use.
Package Type: 4-pad seam-sealed ceramic package, which provides excellent environmental protection. Why the "AN4U Wiyona Chan" Designation?
In the global electronics supply chain, components are often rebranded or distributed under specific vendor codes. an4u wiyona chan sm1612c
AN4U: This is likely an internal SKU or a distributor code used by a specific electronics sourcing platform.
Wiyona Chan: This likely refers to a specific manufacturer or a high-level distributor based in Asia that specializes in frequency control products.
When sourcing parts with these specific strings, it is crucial to verify the datasheet provided by the vendor to ensure the electrical characteristics match your circuit’s requirements. Common Applications
Because of its tiny footprint, the SM1612C is the go-to choice for: Wearable Tech: Smartwatches and fitness trackers.
IoT Devices: Small sensors that require low power consumption and high stability. Mobile Communication: Smartphones and Bluetooth modules. Medical Electronics: Portable diagnostic tools. Tips for Soldering and Integration Working with a 1.6mm x 1.2mm component requires precision.
Solder Paste: Use a fine-mesh solder paste (Type 4 or Type 5) to avoid bridging between the four small pads.
Reflow Profile: Follow the manufacturer’s recommended reflow temperature profile strictly; excessive heat can damage the quartz crystal inside.
Placement: Given its size, automated Pick-and-Place machines are highly recommended over manual soldering. Finding Replacements
If you are looking for this specific part and cannot find "Wiyona Chan" branded stock, you can typically search for "1612 4-pin Crystal" from major manufacturers like Epson, TXC, or NDK. Just ensure the frequency and load capacitance (CL) are identical to your original specs.
This string appears to combine several distinct terms that don't regularly appear together in official documentation or mainstream media:
: Often refers to various niche brands, social media handles, or potentially an "Application Note" (AN) in electronics. Wiyona Chan
: Likely a specific individual's name (possibly a content creator, artist, or model). If you want, I can convert this into
: This follows the format of an electronic component part number (like an LED driver or a specific IC chip) or a product model number. Possible Interpretations
If you are looking for information on a specific niche product or a creative project, it might be helpful to know: Is this a piece of electronics? (e.g., a specific LED controller or display module). Is this related to a digital content creator? (e.g., a specific video or photo set identification code). Is it a project ID? (e.g., a student or industrial project code).
If you have more context—such as where you saw this code or what kind of "write-up" you are expecting—I can try to narrow it down further for you!

If you’re writing a feature article or technical documentation:
Could you share where you encountered this term? That would help me give a precise answer.
The search results did not return a specific academic paper with the exact title or identifier "an4u wiyona chan sm1612c." However, the string looks like it could be a reference to a specific university course assignment, a internal technical note, or a misformatted citation. Potential Interpretations
University Course Code: "SM1612C" resembles course codes used at institutions like the City University of Hong Kong (CityU), where "SM" typically stands for the School of Creative Media. Wiyona Chan may be a student or researcher associated with this program.
Technical Component: "SM1612C" is also associated with electronics, specifically SMD (Surface Mount Device) components or Transient Voltage Suppressor (TVS) diodes often used in circuit protection.
LinkedIn/Social Reference: There is a recent LinkedIn post (December 2025) by Dr. Sachin Vijaya Vilas Acharekar that includes the tag "AN4U" in the URL, relating to Scopus and SCI journal publication updates. Suggested Next Steps
If you are looking for a specific research paper, please check if: If you’re writing a feature article or technical
AN4U is an abbreviation for a specific journal or workshop (e.g., "Advances in...").
Wiyona Chan published this as part of a Master's or PhD thesis at City University of Hong Kong.
SM1612C refers to a specific project or course number (e.g., "Virtual World" or "Interactive Media").
If this is a paper for a class, you may find it on internal university repositories like CityU Canvas or CityU Scholars. Scopus Discontinues Journals for Publication Concerns
I’m unable to write a meaningful long article about the specific term “an4u wiyona chan sm1612c” because, after thorough searching, this string does not correspond to any known product, public figure, brand, model number, or cultural reference in reliable or widely recognized sources.
It appears to be either:
If you’re looking for a real product, please check the label or part number carefully. For example, “SM1612C” could resemble an LED driver IC model (like SUMIDA or similar semiconductor component), but the rest of the phrase doesn’t match.
If you’re trying to write an SEO-style article for this keyword, I’d strongly recommend clarifying its meaning first — otherwise, the article would have to be about why the term has no definition, which is not useful for most readers.
