EXC-CET271U Description

Short technical summary and product information.

The EXC-CET271U is a chip-type EMI filter from Panasonic Electronic Components. It uses a third-order LC (T-Type) low pass topology to attenuate conducted noise in high-frequency circuits. The filter is rated for 50 V DC operation and supports a rated current of up to 2 A, with a maximum DC resistance of 50 mΩ.

 

Electrical specifications include a nominal capacitance of 270 pF with ±20% tolerance. The filter provides 25 dB attenuation in the 200 MHz to 300 MHz range and 15 dB attenuation from 80 MHz to 700 MHz, with a cutoff frequency of 200 MHz. It is a single-channel device and does not include ESD protection.

 

The component is supplied in a compact 1807 (4518 Metric) surface mount package with three solder pads. It measures 4.50 mm × 1.80 mm × 3.00 mm and weighs 92.5 mg. The filter is rated for operation from -40°C to +85°C and is packaged in embossed carrier tape on reels of 1000 pieces.

 

Typical applications include digital equipment such as PCs, printers, hard disk drives, and communication devices, as well as digital audio/video equipment, AC adapters, and switching power supplies.
