Vishay Foil Resistors

Hermetically Sealed High Precision Bulk Metal^®Foil Technology

Resistors with TCR of ꢀ ꢁꢁmꢂ/C, Tolerance of ꢃ0ꢃꢃꢄ ꢅ and

Load Life Stability of ꢃ0ꢃꢃꢆ ꢅ

FEATURES

• Temperature coefficient of resistance (TCR):

Pb-free

2 ppm/°C typical

(- 55 °C to + 125 °C, + 25 °C ref.)

Available

RoHS*

• Power rating: 0.3 to 2.5 W at + 25 °C

COMPLIANT

(depending on model - see table 2)

• Tolerance: to 0.001 %

Any value at any tolerance available within resistance range

• Load life stability: 0.005 % (70 °C for 2000 h at half rated

power)

• Shelf life stability: 2 ppm for at least 10 years

INTRODUCTION

• Resistance range: 5 Ω to 1.84 MΩ (higher or lower values

of resistance available)

The H series resistors are oil-filled, hermetically sealed ultra

precision resistors.

• Electrostatic discharge (ESD) above 25 000 V

• Rise time: 1.0 ns without ringing

• Current noise: < - 40 dB

The hermetic sealing eliminates the ingress of moisture and

oxygen, while the oil acts as a thermal conductor, thus

eliminating long term degradation elements of unsealed

resistors, while at the same time allowing the device to

accept short periods of overload without degradation.

• Thermal EMF: 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Non inductive: < 0.08 µH

Vishay’s Bulk Metal^®Foil outperforms all other resistor

technologies available today for applications that require

precision and stability. When combined with the hermetic

sealing and oil filling, the H series resistors become one of

the most ꢁrecise and stable resistors available.

• Non inductive, non capacitive design

• Non hot spot design

• Terminal finishes available: lead (Pb)-free

tin/lead alloy

• Impervious to harmful environments - oil-filled

With accuracies of 0.001 %, a resistance range from 5 Ω

to 1.84 MΩ, and long term shelf life of less than 2 ppm,

these devices are virtually secondary standards that can be

carried in sets for daily or periodic calibration of factory

measurement equipment.

• Any value available within resistance range (e.g. 1K234)

• Prototype samples available from 48 h. For more

information, please contact foil@vishay.com

• For better performances, please see H series (Z)

Note

Load life stability can be considerably improved through in-house

oriented tests
