Why choose us

Q: What are the differences between the three-pin DR4*10 H-beam inductor and the ordinary two-pin H-beam inductor?
A: The two-pin H-beam inductor is a single-winding power inductor; the three-pin H-beam is a dual-winding primary-secondary integrated structure that can be used for boost conversion and is mostly used in alarm circuit boost circuits.

Q: Can the inductance tolerance of the DR4*10 three-pin inductor be achieved at ±5%?
A: The default is ±10%, and the high-precision version can achieve ±5%, which is suitable for circuits with strict requirements for boost stability.

Q: Where is the DR4*10 three-pin inductor mainly used?
A: It is most commonly used in gas alarmers, smoke alarm buzzer boost drivers, and also in small LED flashing and small household appliance control board boost circuits.

Q: Can the pin length of the DR4*10 three-pin inductor be modified?
A: Yes, it supports lengthening / shortening the pins, which can meet the welding requirements of the customer's PCB board.

Q: Why is the packaging of the DR4*10 three-pin inductor yellow?
A: It is encapsulated with yellow epoxy resin, which has excellent insulation performance, can fix the windings, prevent dust and vibration, and is a commonly used color for alarmer boost inductors in the industry.
