Operating temperature range of -20 to +70C Most UM1/5 modes also available in HC49U/T Formed leads and jacket SM option available for UM1 and UM5 The filters should NOT be exposed to temperature higher than 150C For M series filters, hand solder is required. Use low melting point solder (lower than 160C typical) on the leads, no more than 3 seconds Please consult VTC support for the other specifications not listed above.
