Hermetically Sealed Resistors, Aerospace
FEATURES
• VH102Z Series
Nominal Temperature Coefficient of Resistance:
± 0.2ppm/°C MIL Range (see table 2)
• VHZ555 Temperature Coefficient of Resistance:
± 2ppm/°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 (VHZ555)
• Power Rating: 0.6 Watts at + 70°C; 0.3 Watts at + 125°C
• Resistance Tolerance (Initial Resistance Accuracy):
± 0.005% tightest to ± 1.0% loosest
• Resistance Range:
VH102Z: 100R to 100K
VHZ555: 4R99 to 121K
The "VHZ" series of resistors is the hermetic version of
the molded "Z" 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.
VH102Z is the hermetically-sealed counterpart of the Z201
high-performance molded resistors.
VHZ555 is the
hermetically-sealed version of the Z555, MIL style RNC90Z.
