10 Amp Resettable Fuse with YINT 30V 500

A 10 A trip product for power branches with up to 5 A hold current

YINT 30V-500 answers a common 10 amp resettable fuse search when 10 A means the PPTC trip-current rating. The device carries a published 5.00 A hold rating, trips at a specified 10.00 A level and supports a maximum voltage of 30 V.

That definition matters to customers. The part is intended for power branches whose continuous current fits the 5 A hold window; it is not advertised as a fuse that carries 10 A continuously.

The Product Behind the 10 A Search

YINT 30V-500 is an active radial DIP PPTC with a published 40 A maximum current and 3.00 W maximum power dissipation. Its listed response reference is 14.5 seconds maximum at 25 A under the stated conditions.

This profile is relevant to a branch that normally draws less than the derated 5 A hold value, may experience short permitted peaks, and should limit a sustained higher-current fault.

Power Distribution and Battery Applications

The 30 V ceiling makes 30V-500 a candidate for selected 12 V and 24 V circuits after all tolerances and transients are measured. Examples include battery-powered modules, lighting branches, adapters and low-voltage industrial distribution. The available short-circuit current must remain within the product rating.

For a battery application, review both charge and discharge conditions. A charger fault can produce a different current path from a load short, and the PPTC must coordinate with the battery management system and connector capability.

Continuous 10 A Designs

A circuit that must carry 10 A continuously needs a different selection. The featured 30V-500 has a 5 A hold rating. YINT's public PPTC range currently states hold-current coverage up to 9.0 A, so a true 10 A continuous load should be submitted for a current portfolio and protection-architecture review.

The review should include copper width, connector temperature rise, source impedance and allowable voltage drop. These factors often decide the practical solution before the fuse label does.

YINT Models Around the 10 A Requirement

The comparison below separates three different intents. Use 60V-300 when voltage headroom is more important and the load fits 3 A hold. Select 30V-500 for the defined 10 A trip target. Consider SMD1812L-800-6V only on circuits up to 6 V when the desired current ratings and surface-mount package fit.

This model ladder gives buyers concrete alternatives without describing unequal ratings as equivalents.

Product Selection Summary

Data to Include in a Sample Request

Tell YINT whether 10 A is a trip target, a startup pulse or the continuous load. Add the operating voltage, hot-state load current, peak duration, fault current and mounting preference. A current waveform is especially useful for motors, heaters and large input capacitors.

Evaluate the recommended sample on the production PCB. The test should confirm normal voltage drop, hot-load stability, the intended fault response and recovery after power is removed.

FAQ

1. Does YINT 30V-500 hold 10 A continuously?

No. Its published hold current is 5.00 A. The 10.00 A value is the trip-current rating.

2. Where does 30V-500 fit best?

It is a starting point for power branches up to 30 V whose continuous load fits the derated 5 A rating and whose intended trip rating is 10 A.

3. What trip-time value is published?

The product page lists 14.5 seconds maximum at 25 A under its stated test condition.

4. Is there a YINT surface-mount option with a higher hold rating?

SMD1812L-800-6V provides 8 A hold and 16 A trip in an 1812 package, but its maximum voltage is only 6 V.

5. Can I use 30V-500 on a 24 V rail?

Only after confirming that tolerance and every relevant transient remain below 30 V and that the fault current and temperature are within specification.

6. What should a 10 A continuous-load customer do?

Send YINT the full load and fault profile for a current product check and an appropriate protection recommendation.

Conclusion

YINT 30V-500 is the clearest product match when a 10 amp resettable fuse search means 10 A trip current. Its 5 A hold and 30 V ratings define the usable window. A continuous 10 A load requires a separate YINT review, while 60V-300 and SMD1812L-800-6V serve different voltage and current priorities.
