Snubber and Filter Capacitor Series’ are Double Metallized Polypropylene, Non-Inductive Wound with a Flame Retardant Case
New Yorker Electronics has announced the release of two new series of self-healing capacitors from ASC Capacitors. The new BLF (Board Level Filter) and BLS (Board Level Snubber) Capacitor Series consist of double-sided metallized polyester film electrodes and are non-inductive wound, yielding no inductance value.
BLS – Board Level Snubber Capacitor
The new ASC Capacitor BLS Series has high density packaging and is suited for high frequency, high pulse and high AC 
voltage applications. It has a uniform shape in a case that is not only flame retardant but also impervious to all known solvents. The BLS has a dielectric strength of 160% of rated voltage for two seconds, tolerances between ±5% and ±20% and insulation resistances of C<0.33 µF, R≥30,000 MEG. OHM @ 20 ±3°C and C≤0.33µF, RC≥10,000 MEG.OHM X µF. It comes standard in voltages of 630Vdc (400Vac), 1200Vdc (600Vac), 1600Vdc (650Vac) and 2000Vdc (700Vac) with a capacitance range between 0.0022 and 3.3 µF. Custom dimensions are available upon request.
This line of snubber capacitors includes designs and features for a wide variety of applications including electronic lighting (car headlamp, ballast), switching spikes suppression in SMPS, snubber and SCR commutating circuits and high frequency and high voltage applications.
BLF – Board Level Filter Capacitor
The new ASC BLF Series is also a Metallized Polypropylene AC Filter Capacitor with Non-Inductive Winding. It provides high reliability and enhanced self-healing characteristics with low losses and low ESR. Like the BLS, the BLF has an operating temp between -40°C ~ +105°C. They come standard with voltage ranges of 180V, 275 and 350V. 
The capacitance range is standard at 1.0 ~ 70.0µF, with other ratings reviewed on request. The BLF Series has a dielectric strength of 160% of rated voltage for two seconds and capacitance tolerances between ±5% and ±20%.
Also similar to the BLS, it has a low dissipation factor and a high insulation resistance. The BLF is suitable for AC output filtering in such applications as UPS, Solar Photovoltaic DC/AC inverters with an inductor-capacitor-inductor, or LCL, filter.
