HIGH FREQUENCY MAGNETICS
T1/E1 Mini-Octal Transformer Module
TM01107
• Optimized for paralleled receive line inputs
• Operating temperature range: -40° to +85°C
• Eight transformers in a single surface-mount package • Meets IEC 695, 202 flammability requirements
• Mini-octal 32-pin platform provides 33% area reduction • PWB Process Capability: standard printed wiring board
compared to standard octal package
assembly techniques, total-immersion cleaning
• Tight ratio tolerance assists impedance matching
• Reliability testing: Shock, vibration, temperature cycling,
temperature - humidity - bias
• RXI meets ITU-T G.703 return loss requirements when
RXO is terminated in 102Ω
• Interwinding breakdown voltage: 1500 Vrms min
