| TFG * 10/100 Base-T Single Port Transformer Module Features * Low profile and light weight 10/100 BaseT modules facilitate pick and place compatability and speed of placement * Meets requirements of IEEE 802.3u and ANSIX3.263 * Consistent and reliable coplanarity * Footprint compatible with Gigabit Ethernet layout * Manufactured in an ISO-9001:2000, TS-16949:2002 and ISO-14001:2004 certified Talema facility * Fully RoHS compliant and meets lead free reflow level J-STD-020C Electrical Specifications @ 25C Inductance: 350H minimum @ 100kHz, 100mV, 8mA Minimum isolation voltage: 1500 Vrms Operating Temperature Range: -40C to +85C Storage Temperature: -40C to +125C Standard Packing: Tape and Reel 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.
