Soldering Recommendations
Because the TMOV
device, care must be taken when soldering the devices into place. Two
soldering methods are possible. Firstly, hand soldering: It is recommend-
ed to heat-sink the leads of the device. Secondly, wave-soldering: It is
critically important that all preheat stage and the solder bath tempera-
tures are rigidly controlled. The recommended solder for the TMOV and
i TMOV varistors is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37(Sn/Pb).
Littelfuse also recommends an RMA solder flux.
Ordering Information
NOTE: By ordering the standard part number, i.e. TMOV20R150E, standard
lead styles, packing and lead spacing will be supplied. These specifications are
as follows:
• Straight Leads
• Bulk Packed
• 7.5mm Lead Spacing
• Leads not in-line except parts > 420 V. See table on page 34.
Tape and Reel
• Add suffix L2T7 to the end of standard part number (ex. TMOV20R150EL2T7)
• Tape and Reeled parts have in-line, crimped leads. This excludes the varistor
lead on i TMOV devices which are not crimped and not in-line. See drawings on
page 35.
