The design and laser adjustment of the resistive element optimises the limiting element voltage of the resistor. Terminations The chips are supplied with wrap-around terminations suitable for soldering. Consult factory for alternative termination options. Solderability The terminations have an electroplated nickel barrier and tin finish. This ensures excellent ‘leach’ resistance properties and solderability. Marking The body protection is resistant to all normal cleaning solvents suitable for printed circuits. The chips are not marked and the relevant information on type, value, tolerance date code and quantity are recorded on the reel. 2512 □≤100M: -5 2512 >100M: -15 2512 □≤100M: -1.5 2512 >100M: -8 500 1000 1500 2000 2500 3000 3500 0.01 0.1 1 10 100 1000 Voltage (V) Resistance Value (MΩ) Maximum Continuous Voltage HVC1206 HVC2010 HVC2512 Commodity Chip 0.01 0.1 1 10 100 1000 Peak Voltage (kV) Resistance Value (MΩ) Lightning Strike Performance 1206-1.2/50µs 1206-10/700µs 2010-1.2/50µs 2010-10/700µs 2512-1.2/50µs 2512-10/700µs Note: maximum peak voltage tested was 6kV; performance beyond this is estimated.

Electrical connection to a ceramic substrate or to a printed circuit board can be made by reflow or wave soldering of wrap-around terminations. Wrap-around terminations provide good leach properties and ensure reliable contact. Due to the robust construction, the HVC can be immersed in the solder bath for 30 seconds at 260°C. This enables the resistor to be mounted on one side of a printed circuit board and wire-leaded components applied on the other side. HVC resistors themselves can operate at a maximum temperature of 155°C (see performance above). For soldered resistors, the joint temperature should not exceed 110°C. This condition is met when the stated power levels at 70°C are used. The PCB layout should avoid tracks running between the HVC mounting pads, as this would compromise the LEV. The LEV stated applies to operation at sea-level pressure, in a non-condensing atmosphere and non-contaminating environment. Voltage derating should be applied if low pressure, high humidity or contamination may be encountered. The termination clearance dimension (B) should be used in conjunction with the creepage limit applicable to the circuit application in order to determine the derated LEV.
