IP4252CZ8-4-TTL,13

Overview

The IP4252CZ8-4-TTL,13 is an integrated 4-channel passive RC low-pass filter network with ElectroStatic Discharge (ESD) protection. It utilizes a Pi-type RC topology with a resistance value of 40 Ohms and a total capacitance of 12 pF per channel. The device provides ESD protection up to ±30 kV contact discharge according to IEC 61000-4-2 standards. It is housed in a 16-pin ultra-thin leadless Quad Flat No-leads (QFN) plastic package with a 0.4 mm pitch and a height of 0.55 mm.

Feature Summary

• Integrates four independent RC low-pass filter channels for RF signal attenuation on I/O ports.
• Incorporates diodes to protect downstream components from high-voltage electrostatic discharge events.
• Fabricated using monolithic silicon technology within a compact, ultra-thin QFN package.

Applications

• Cellular phone and Personal Communication System (PCS) mobile handsets
• Cordless telephones
• Wireless data (WAN/LAN) systems
• Mobile Internet Devices (MID)
• Portable Media Players (PMP)

Procurement Notes

Verify the specific ordering suffix, such as ,13, which indicates tape and reel packaging configuration. Confirm RoHS compliance and halogen-free status against current manufacturing records. Check component availability status as some listings indicate obsolete status. Ensure the 16-pin QFN footprint matches the design layout requirements.

Selection Notes

Select this component when designing portable communication devices requiring simultaneous EMI filtering and ESD protection on multiple I/O lines. The 40 Ohm resistance and 12 pF capacitance values are suitable for attenuating unwanted RF interference while maintaining signal integrity. The ultra-thin profile supports space-constrained mobile applications.
