Description

This article focuses on the electronic component model RC0603JR-07180KL, which belongs to the product category of chip resistors - surface mount.

Specifications and features

The RC0603JR-07180KL is a Triac dimmable GU10 12V/400mA buck LED driver EV board. It utilizes a tapped transformer to increase power conversion turn-on duty cycle, boost current back to LED during the ratio of tapped winding. This model also allows for the use of larger gauge wire and large inductance in the switching loop, which reduces the switching current and forward drop. As a result, a Schottky Barrier Rectifier (SBR) diode can be used to reduce power consumption on the diodes.

Key features of the RC0603JR-07180KL include:

• Typical 3% to 95% dimming performance (depends on dimmer brands)
• Boundary conductive switching mode
• Simple adjustable constant current
• Inductor short protection
• Low BOM cost
• PFC >0.9 & low THD
• 200~265VAC input range
• >77% efficiency
• LED protection against open, short, and wrong polarity

Application Scenarios

The RC0603JR-07180KL is commonly used in the following scenarios:

• GU10 LED offline small size bulb
• Candle size LED lamp
• Desktop lamps
• Under the counter lamps
