Product may not
be to scale
• VHS102 Series
Nominal Temperature Coefficient of Resistance:
+ 0.6ppm/°C (0°C to + 25°C);
– 0.6ppm/°C (+ 25°C to + 60°C);
+ 2.2ppm/°C (– 55°C to + 25°C);
– 1.8ppm/°C (+ 25°C to + 125°C)
The "VH" series of resistors is the hermetic version of sev-
eral molded "S" series devices. Hermetic sealing eliminates
the ingress of both oxygen, which degrades resistors over
long periods, and moisture which degrades resistors more
quickly. These parts are made with glass to metal seal
enclosures employing Kovar eyelets which allow the copper
leads to pass through the enclosure to minimize the thermal
EMF from the lead junctions. Rubber fill between the metal
housing and resistance element acts both as a mechanical
damper and thermal transfer path.
• VHS555 Temperature Coefficient of Resistance:
± 5ppm/°C (– 55°C to + 125°C);
• Selected TCR Tracking: to 0.5ppm/°C (matched sets)
• Load-Life Stability: ± 0.0025% maximum ∆R at 0.1 watt,
+ 60°C, 2,000 hours (VHS555)
• Power Rating: 0.6 Watts at + 70°C; 0.3 Watts at + 125°C
VHS102 and VH102K are the hermetically-sealed counter-
part of the S102C and S102K high-performance molded re-
sistors. VHS555 is the hermetically-sealed version of the
S555, MIL style RNC90Y.
• Resistance Tolerance (Initial Resistance Accuracy):
± 0.005% tightest to ± 1.0% loosest
• Resistance Range: 1Ω to 150KΩ
