Turns and Impedance Characteristics

When the desired performance of an EMI core cannot be obtained with a single pass through the core, the impedance characteristics can be changed with multiple turns.

A turn is counted by the number of lead-wire windings which pass through the inner hole of the core. Windings on the outside of the core do not count.

 

Core Material and Effective Frequency Range :

There are two ferrite material options for KEMET EMI Cores: Nickel-Zinc (Ni-Zn) and
Manganese-Zinc (Mn-Zn). Each core material has a different resistance and effective
frequency range. The Mn-Zn core material has lower resistance compared to the Ni-Zn; therefore, be sure to provide adequate insulation before use.

PRC207 Datasheet PDF – Terminator and Local EMI/RFI Filter

Posted on by pinout

Part Number: PRC207

Function: Clock terminator and local EMI/RFI Filter

Package: 3-Pin SOT-23 type

Manufacturer: California Micro Devices ( Onsemi )

Schematic :

PRC207 datasheet

Description

High speed microprocessors like Intel’s Pentium , DEC’s Alpha, Motorola’s 68K and  owerPC, Sun’s SPARC, MIPs, and other RISC-based systems require well controlled and precise clock signals to maintain a high performance synchronous system. However, very fast edge rated clock signals exhibit transmission line effects on the clock lines resulting in undershoot and overshoot disturbances.

CAMD’s PRC207 SOT resistor-capacitor integrated thin film networks are specifically designed to eliminate transmission line effects on high speed clock and data lines. They are effective in suppressing EMI/RFI noise at I/O ports and can also be used as “distributed” AC terminators when filtered lines are dispersed across the board.

 

Features

1. Filters at source of emissions
2. Stable resistor-capacitor network
3. Ideal for high-speed logic
4. Low lead inductance
5. Reduces board space compared to discretes

Applications

1. Clock termination
2. Point of contact filtering
3. Low pass filtering
4. EMI/RFI filtering
