Please note that customers need laser trimming equipment. Trimming by laser increases the initial resistance. Amount of resistance increase is dependent on the laser cut configuration as shown. W1 must not exceed 1/2W to ensure power rating of the unit. Specifications given herein may be changed at any time without prior notice.
