SPECIFICATION OF BA4A-11 SERIES
FEATURES
1. Availing in a wide range of impedance values and
providing excellent EMI suppression characteristics
for various types of noise.
2. Availing in 4 lines by a single smallest SMT chips, it can very
usefully adopted in high density circuit designs. specially
ultra low profile only 0.5mm for thinner designed product.
3. Heat generation and crosstalk between adjacent
circuits is minimized.
4. Excellent solderability.
APPLICATIONS
1. Waveform correction in personal computers, electric
equipments, communication equipments, OA equipments,
and provides radiated noise countermeasures in interfaces and harness connecting parts.
Best replacement of mini resistor array.
2. Prevents noise intrusion in videos, LCD, camera & smart phone, Pad, module, etc.
3. Parallel signal line.
