Metal foil resistor material is bonded onto an alumina substrate and connected to wraparound terminations with nickel barrier and 100% Sn finish. Protec- The unadjusted resistors are heat treated to give the required TCR and stability, then a precisely controlled laser trim process adjusts tion and marking are applied and each resistor is measured immediately before packing into tape. the resistance value. Epoxy protection is applied and wrap-around terminations are added and plated with Nickel then Tin. Each Marking resistor is measured immediately before packing into tape. MFC0402 parts are not marked. Larger MFC sizes are marked with 2, 3 or 4 characters indicating ohmic value. Where R is used it indicates the decimal point location for the value in ohms, e.g. R047 = 47m, R01 = 10m. Where R is omitted, the value is in milliohms e.g. 047 = 47m, 03 = 3m. Terminations Reels are marked with type, value, tolerance, date code and quantity. The standard termination is 100% Sn matte plated wrap-around suitable for soldering. SnPb plated option is available for standard Solvent Resistance range PCF over the restricted range below. The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits.

Application Notes of a printed circuit board and wire-leaded components HDSC resistors are ideally suited for handling by automatic applied on the other side. HDSC is compatible with methods due to their rectangular shape and the small dimensional tolerances. Electrical connection to a ceramic typical Pb-free soldering materials and temperature substrate or to a printed circuit board can be made by reflow profiles. or wave soldering of wrap-around terminations. HDSC resistors themselves can operate at a maximum temperature of 155C. For soldered resistors, the joint Wrap-around terminations provide good leach properties and temperature should not exceed 110C. This condition is met ensure reliable contact. Due to the robust construction, the when the stated power levels at 70C and recommended pad HDSC can be immersed in the solder bath for 30 seconds and trace areas are used. Pad and trace area is defined as the total area of the solder pad plus all copper trace within two at 260C. This enables the resistor to be mounted on one General Note squares of the edgeBI T of theechnologies IR solder pad.
