PPCs filters deliver unsurpassed mechanical and electrical performance to meet the challenging requirements of todays digital cable, telephony, and high-speed data systems. PPC's forward path attenuators provide a fixed level of attenuation within the downstream frequencies without affecting upstream frequencies. Typical applications include attenuation of over amplified signals generated by drop amplifiers at the first input. Easy to read numbered labeling comes standard with optional color coding available. Hermetically sealed to prevent moisture migration.Precision four-point female seizure contact.100% Surface Mount Technology for consistent performance.
