New PCNM Series of Precision Non-Magnetic Thin Film Chip Resistors Deliver High Power Ratings to 6 W in Small Sizes
The News:
Vishay Intertechnology introduces a new series of high-power, surface-mount, precision non-magnetic thin film chip resistors. Built on aluminum nitride substrates, the Vishay Dale Thin Film PCNM series offers power ratings of 2 W and 6 W in compact 1206 and 2512 case sizes, respectively.
- Provide four times the power handling capability of previous-generation non-magnetic resistors
- Enlarged backside terminations reduce the thermal resistance between the topside resistor layer and
- the solder joint on the end user’s circuit assembly
- Non-magnetic properties eliminate the effects of stray magnetic fields on circuit performance in X-ray and MRI machines, while correcting passive intermodulation issues in cell phone base stations and amplifiers
Product Benefits:
- High thermal conductivity aluminum nitride substrate
- Non-magnetic
- Power ratings up to 6 W
- Available in compact 1206 and 2512 case sizes
- Low TCR down to ± 25 ppm/°C
- Laser-trimmed tolerances to ± 0.1 %
- Wide temperature range of -55 °C to +155 °C
- Wide range of resistance values from 2 Ω to 30.1 kΩ
- Low noise of < -30 dB
- Low voltage coefficients of < 0.1 ppm/V
- Voltage ratings from 75 V to 200 V
- Flame-resistant in accordance with UL 94 V-0
- Available with lead (Pb)-bearing and lead (Pb)-free, RoHS-compliant terminations
The Key Specifications:
| Case size | Power rating (W) | Working voltage (V) | Resistance range (Ω) |
