Chip inductors in tiny 0402 package

28 May 2008 Passive Components

Murata has released the BLM15P series of chip ferrite bead inductors in 0402 packages. These tiny parts measure 1,0 by 0,5 by 0,5 mm, achieving a footprint that is over 60% smaller than the 0603 types offered previously, without any degradation in performance. The devices are suitable for EMI reduction on DC power lines and low-speed signal lines where the smaller packaging reduces board space.

The inductors feature extremely low DC resistance, between 0,035 and 0,090 Ω, and high rated current of up to 2,2 A. The typical impedance at 1 MHz is between 10 Ω and 120 Ω, depending on the specific part. The equivalent circuit is a series inductor and resistor, the resistance element becoming dominant at high frequencies. The BLM15P series has an operating temperature range of -55 to +125°C, with current derating becoming necessary above 85°C.
