Low DF and DC Leakage
Temperature Stable
260 ºC for 10 Seconds Soldering
Meets IECQ Standard
QC300801/US0001
Meets EIA Standard 535BAAC
The T491 Series’ physical outline and dimensions conform to the global standard for tantalum capacitor chips, and the T491 exceeds the
requirements of EIA standard 535BAAC. T491
chips are specifically for automated surface
mount processes and equipment. The terminations are Tin-Lead (SnPb) and 100% Matte-Tin
terminations are also available. Reliability and
thermal stability are assured by lead-frame attachments to the tantalum pellet made by microprocessor-controlled welding and a high temperature silver epoxy adhesive. Standard packaging is compatible with all tape-fed placement
units and with EIA RS- 481-1 tape and reel specification.
