🚗 Automotive-Grade Series
Viking's AEC-Q200-qualified lineup covers anti-sulfuration thick-film, precision thin-film, current-sense, array, and MELF types — used in automotive lighting, infotainment, power systems, and instrument clusters. Representative parts include ARM.A (automotive thin-film precision) and CSRV (automotive MELF).
How to Read Viking Part Numbers
Using the AR thin-film precision series as an example:
AR 03 T T B Y 1001 N
| Field | Meaning | Example |
|---|---|---|
| AR | Series | Thin-film precision chip resistor |
| 03 | Size | 03 = 0603 |
| T | Tolerance | T = ±0.01%, A = ±0.05%, B = ±0.1% |
| T | Packaging | T = tape & reel |
| B | TCR | 5 = ±1, B = ±10, D = ±50 ppm/℃ |
| Y | Power | N = 1/20 W, Y = 1/16 W, X = 1/10 W |
| 1001 | Resistance | E96 4-digit code; 1001 = 1 kΩ |
| N | Marking | N = no marking |
Source: Viking official datasheets and distributor identification guides. Lead-type resistors follow different conventions — e.g., MFR0318BTNW1001 decodes to MFR, 0318 body, ±0.1%, ±15 ppm/℃, 1/8 W, 1 kΩ.
Competitive Positioning
Viking sits between top-tier Japanese suppliers (KOA, ROHM) and emerging domestic brands — offering near-premium electrical performance with faster customization response and a more competitive price structure. The brand is especially well received in medical instruments, test & measurement, automotive electronics, and communication infrastructure, where precision and reliability matter but cost pressure is real.
