Electrolytics live longer with lower ESR

Manufactured by Nippon Chemi-Con and available from Young ECC, the KY series aluminium electrolytic capacitors employ a newly developed electrolyte to minimise ESR.

Manufactured by Nippon Chemi-Con and available from Young ECC, the KY series aluminium electrolytic capacitors employ a newly developed electrolyte to minimise ESR.

Capacitance values available cover 22 to 18,000uF.

Life has been extended from the earlier 3 to 6kh.

It now spans 4kh at 105C with rated ripple in a 5 to 6mm diameter can through to 10kh at 105C with rated ripple in a 5 to 18mm can.

Low ESR and impedance make this range of capacitors ideal for high-frequency use.

At 50V, 20C, 100kHz, 22uF capacitors exhibit an impedance of 0.70ohms, whereas 2700uF capacitors have an impedance value 0.014ohm.

Other specifications include 6.3 to 50V rated voltage range, temperature range of -40 to +105C, low leakage current, excellent low temperature characteristics and +/-20% capacitance tolerance.
