Sumida’s upgrade to popular power inductor series

New Yorker Electronics has announced its distribution of the new Sumida CDRH12D78E/LD Power Inductor.

This new model is an upgrade to the CDRH127/LD and is more cost effective despite an increased capacity. The magnetically shielded power inductor is ideal for DC/DC converters such as a Buck-Boost, a single-ended primary-inductor converter (SEPIC) and Zeta for non-automotive applications – all of which can deliver a voltage either below or above the regulated output voltage.

The new CDRH12D78E/LD Sumida Power Inductor has twenty-three possible variations with differing inductances, saturation currents and DCR. Inductance values from 1.00uH through 1000uH are higher than the prior model, which also registers an increased DCR that ranges from 6.50 to 1500m. The saturation current (Isat) is 20A max. (typ.) for the lowest inductance model and drops to 0.85 for the highest inductance value.

The new CDRH has an increased temperature range while maintaining a small footprint.  The increased temperature range is from -40°C to 105°C, including the coil’s self-temperature rise. The temperature rise current (Irms) is available in ranges from 14.2A to as low as 0.82 with the 1000uH model. The small 12.5mm × 12.8mm × 8.0mm packaging is only 3.9 grams and is available at 500 pieces per reel.
