Capacitor's Symmetrical Design Reduces ESL to 1 nH

AVX Corporation has expanded its TPM Series to include D and low profile Y case size multi-anode ‘mirror’ configuration tantalum capacitors. Appropriate for telecommunication infrastructure, networking, servers, and military and aerospace applications, the TPM mirror tantalum capacitor delivers low self-in ductance (ESL) and lower equivalent series resistance (ESR) in a small package. The new symmetrical design reduces the ESL to 1 nH, half that of standard D case sized devices. Low ESL enables a higher resonant frequency up to 500 kHz (mirror D case), delivering more efficient filtering in DC/DC power switching converters. The new design also reduces the height of the new tantalum capacitors from 4.3 mm (E case) to 3.1 mm (D case) with further reductions down to 2.0 mm maximum height (Y case).
