SM91502ALA BMS Transformer

Product catalog summary
Overview: The SM91502ALA BMS Transformer is designed for use with specific models from Analog Devices, NXP, and Texas Instruments. It features a single channel with an integrated choke and is compliant with AEC-Q200 and RoHS standards.
Specifications:
  • Electrical: Operating voltage is 1000 VDC with a Hi-Pot of 4300 VDC. The transformer has a turns ratio of 1:1 ± 2% and operates within a temperature range of -40 °C to +125 °C.
  • Inductance: OCL ranges from 150 to 450 µH at 100 kHz, with a maximum leakage inductance of 0.5 µH.
  • Resistance: Transformer side DCR is 0.45 Ω max, and CM choke side DCR is 0.85 Ω max.
  • Performance: Insertion loss at 4 MHz is -0.25 dB max, with a return loss of -22 dB min. Common mode rejection ratio is -35 dB min for 1~100 MHz and -28 dB min for 100~200 MHz.
Packaging: The transformer is available in tape and reel packaging with 800 pieces per reel.
Soldering Profile: The reflow condition for Pb-free assembly includes a peak temperature of 245 - 250 °C, with a maximum ramp-up rate of 3 °C/second and a ramp-down rate of 6 °C/second.
Legal Disclaimer: The document includes a disclaimer regarding the use of Bourns products, emphasizing the need for users to verify product performance in specific applications and noting restrictions on use in critical applications without explicit approval.
