Applications
Talema 10BaseT Quad transformer modules contain transmit and receive isolation transformers to maintain consistant wave shape and suppression of common
mode noise while providing equipment isolation per IEEE 802.3. High impedance common mode quad chokes for additional EMI suppression have been added
on some models as required for FCC and CISPR 22 Class B certification.
Quality and consistency is guaranteed through 100% testing of the specified parameters for primary inductance, leakage inductance, turns ratio, DC resistance and
interwinding capacitance.This ensures that the return loss and pulse wave shape requirements can be fully maintained. Additionally, all parts are tested for 1500V
minimum isolation.
Test Frequency: Inductance, Interwinding Capacitance and Leakage
Inductance measured @ 100kHz/20mVrms
Quad Choke: 36H; Turns Ratio: 1:1:1:1
Standard packing in tape and reel
Ordering Information:
TMQ-XXX- * X
* Specify common mode noise suppression choke preference - the schematic letter designation should be inserted from coulmns 1, 2 or 3
1.
The first column - common mode choke on both the Tx and Rx transformers
2.
The second column - common mode choke only on the Tx transformer
3.
The third column - common mode choke not included in module
