15 Amp Resettable Fuse Selection with YINT SMD1812L 800 6V

A compact 16 A trip product for low-voltage boards

For customers using 15 amp resettable fuse to describe a trip threshold, YINT SMD1812L-800-6V is a close catalog candidate. The active 1812 surface-mount PPTC has an 8.00 A hold rating, a 16.00 A trip rating and a 6 V maximum voltage.

The product is aimed at low-voltage boards whose normal current fits the 8 A hold window. It should not be presented as a device that carries 15 A continuously.

A Product Close to a 15 A Trip Target

SMD1812L-800-6V has a published 50 A maximum current and 2.00 W maximum power dissipation. At 30 A, the listed maximum trip time is 2 seconds under the stated test conditions. This makes the model relevant when a low-voltage design needs a transition region near 15 A and a compact surface-mount package.

A startup peak near 15 A is a separate case. Its duration must be compared with the full time-current curve so that valid load behavior does not cause a trip.

Low-Voltage Board Applications

The 6 V limit directs this part toward single-cell battery equipment, low-voltage DC modules, charging accessories and board-level distribution. It is not a candidate for 12 V or 24 V rails. Charger tolerance and any inductive overshoot must remain within the rating.

The 1812 format supports automated assembly. High current still requires suitable pad geometry and copper area because PCB temperature affects both voltage drop and trip behavior.

Options Below the 16 A Trip Level

YINT 30V-500 provides a lower 10 A trip rating with a higher 30 V ceiling, while 60V-300 provides 6 A trip and 60 V maximum voltage. These through-hole parts serve higher-voltage, lower-current branches. SMD1812L-800-6V remains the focused choice when the board is limited to 6 V and needs the 8 A hold and 16 A trip combination.

Showing the models together lets a customer choose by voltage and trip target instead of assuming that a higher ampere label is always better.

YINT Model Comparison

The table is organized by electrical window. It helps distinguish the near-15 A trip requirement from a higher-voltage need, and it shows which products require through-hole or surface-mount assembly.

Product Selection Summary

When the Continuous Load Is 15 A

A 15 A continuous load exceeds the featured device's 8 A hold rating and the 9.0 A upper hold-current coverage stated for YINT's public PPTC range. Send the full load and fault profile to YINT for a current product check or a different protection recommendation.

Do not create the rating by simply paralleling PPTCs. Resistance tolerance and self-heating can produce unequal current sharing. Any parallel arrangement requires a reviewed thermal and current-sharing design.

FAQ

1. Which YINT model is closest to a 15 A trip rating?

SMD1812L-800-6V has a published 16.00 A trip rating and 8.00 A hold rating.

2. Can this model carry 15 A continuously?

No. Its hold-current rating is 8.00 A. A continuous 15 A design needs a separate product and system review.

3. What is the maximum voltage?

The SMD1812L-800-6V maximum voltage is 6 V, so it is limited to low-voltage circuits.

4. How fast does it trip at 30 A?

The product page lists a maximum trip time of 2 seconds at 30 A under the stated conditions.

5. What YINT model offers a higher voltage rating?

30V-500 raises maximum voltage to 30 V with a 10 A trip rating, while 60V-300 raises it to 60 V with a 6 A trip rating.

6. Can two devices be connected in parallel?

Parallel PPTCs do not automatically share current evenly. Use such an arrangement only after a specific current-sharing and thermal review.

Conclusion

YINT SMD1812L-800-6V is the most relevant catalog model when a 15 amp resettable fuse search means a trip target near 15 A on a circuit up to 6 V. Its actual ratings are 8 A hold and 16 A trip. Higher-voltage or continuous 15 A requirements should move to a different YINT model review rather than stretching this product beyond its published window.
