  1. Preferred Termination style fo r current 1-1/4 inch rectilinear trimmers (staggered PC pins present a sturdier mounting arrangement for shock, vibration, and impact situations). 2. 10 W at ± 5 % available on special order. 3. Maximum TCR applies to the 3 σ (sigma) limit or 99.73 % of a production lot. (Measured end-to-end with wiper off the element.) 4. Measurements of TCR through the wiper are influenced more by setting stability and the percentage of the total resistance in use (at the wiper) than by fundamental resistance change due to temperature alone. The parameter shown in Table 3 is a 2 σ distribution typifying the behavior of the device when used with 40 % or more of the total resistance in use. 5. Derated linearly from full power at + 85 °C to zero (0) W at + 150 °C. See Figure 3 in this data sheet. 6. All ΔR’s are measured to the tolerance specified + 0.01 Ω. 7. Whichever is greater. 8. Load-Life test performed at nominal rated power, 0.5 W, at + 85 °C. Special Available Options: Special marking Special lengths for lead wires (L, LB Style) Hooked leads Alternate bushing and PC combinations Power conditioning and screening operations VISHAY TRIMMERS ARE INSPECTED 100 % for:  Short-time overload (6.25 x rated power for 5 s on; and for 30 s off - 3 cycles)  Immersion  Resistance tolerance check  End resistance  Visual-mechanical  Dynamic tests for continuity, CRV By Sample for: T C R D W V TABLE 5 - COMPARISON MIL-PRF-22097/2 CHARACTERISTIC F7) 1202 MAXIMUM (Worst Case) TEST GROUP I Visual and mechanical Total resistance Actual effective electrical travel End resistance Contact resistance variation - CRV (noise) Dielectric withstanding voltage - DWV (atmospheric and barometric pressure) Insulation resistance Shaft torque Thermal shock No failures ± 10 % 17 to 27 turns ± 2 % or 20 Ω ± 3.0 % or 3 Ω7) Per MIL-STD-202, methods 301 and 105 ≥ 1000 MΩ 8 oz. in. maximum ± 1.0 % No failures ± 10 % 25 ± 2 turns 2 Ω 3 Ω typical, 10 Ω maximum Per MIL-STD-202, methods 301 and 105 ≥ 1000 MΩ 8 oz. in. maximum ± 1.0 % TEST GROUP II Resistance temperature characteristic - TCR Moisture resistance Contact resistance variation - CRV (noise) ± 1.0 % 3.0 % or 3 Ω ± 0.5 % 3 Ω typical, 10 Ω maximum TEST GROUP III Shock (specified pulse) Vibration (high-frequency) Contact resistance variation - CRV (noise) Salt spray ± 1.0 % ± 1.0 % ± 3.0 % or 3 Ω No corrosion ± 0.5 % ± 0.5 % 3 Ω typical, 10 Ω maximum No corrosion TEST GROUP IV Solder heat Life (1000 h at + 85 °C)8) Contact resistance variation - CRV (noise) ± 1.0 % ± 2.0 % ± 3.0 % or 3 Ω7) ± 0.05 % ± 0.5 % 3 Ω typical, 10 Ω maximum TEST GROUP V Low-temperature operation High-temperature exposure Contact resistance variation - CRV (noise) ± 1.0 % ± 2.0 % ± 3.0 % or 3 Ω ± 0.5 % ± 0.5 % 3 Ω typical, 10 Ω maximum TEST GROUP VI Rotational life Contact resistance variation - CRV (noise) Terminal strength ± 2.0 % ± 3.0 % or 3 Ω 2 lbs ± 2.0 % 3 Ω typical, 10 Ω maximum 2 lbs TEST GROUP VII Solderability (excluding termination L) Immersion (excluding termination L) MIL-STD-202 method 208 No continuous stream of bubbles MIL-STD-202 method 208 No continuous stream of bubbles TEST GROUP VIII Fungus MIL-STD-810 method 508 No mechanical damage MIL-STD-810 method 508 No mechanical damage
