Polymer tantalum capacitors reduce resistance
AVX's 1210 B case sise TCJ series of polymer tantalum capacitors launched last year are now available with even lower ESR, reduced from 70 to 45mohm.
AVX's 1210 B case size TCJ series of polymer tantalum capacitors launched last year are now available with even lower ESR, reduced from 70 to 45mohm. For the design engineer this means lower output noise and improved ripple current in their circuits. It also means, faster pulse energy in key areas of the circuit, which has become much more important with the increased usage of battery power for handheld equipment.
Devices offer 100uF capacitance at 6.3V and are part of the only family of polymer devices on the market capable of withstanding the lead-free requirement for reflow at 3x260C.
The company guarantees operation up to 125C, with parts offering a defined ESR specification after reflow soldering.
They also exhibit a safer nonignition failure mode as well as improved capacitance retention compared with conventional MnO2 electrode capacitors.
The new capacitor will be ideal for designers of small 4.5-5.5V battery-operated handheld equipment such as mobile phones, PDAs, MP3 players and digital cameras.
