Walsin Passive Components Held in Hong Kong Stock
What Venatech holds in Hong Kong from the Walsin catalogue: 1,126 stocked part lines across MLCC, chip resistor, safety capacitor and inductor.
Anti-Sulfuration Resistors: SF Thin Film and SA Thick Film Arrays
Walsin’s 56,227 anti-sulfuration resistors sit in nine series under five part-number prefixes. SF thin film and SA arrays compared field by field.
Tantalum Nitride Thin Film Resistors: The Walsin MF Series
Walsin’s tantalum nitride MF series is 20,520 parts, every one 1206 and every one 2/5 W. 1,026 resistance values times 5 tolerances times 4 TCR grades.
Precision Thin Film Resistors: ±0.01% Tolerance and ±3 ppm/°C TCR
Walsin WF thin film reaches ±0.01% and ≦±3 ppm/°C. 52,808 of 58,314 parts are ±0.01%. Compared field by field against high precision thick film.
Chip Attenuators: Reading a Pi-Type Part Number
Decode a Walsin chip attenuator part number field by field: WA04P prefix, dB code, accuracy letter. All 23 parts, 0 to 20 dB at 0402 into 50 ohms.
Chip Resistors Above 10 Megohm: A Selection Checklist
Walsin’s thick film range stops at 10 megohms. Its 488-part High Ohm group reaches 100 megohms – what it holds, what it does not, and what to check.
Trimmable Chip Resistors: Designing for Laser Trim
How to specify a Walsin trimmable chip resistor: 0/-10%, 0/-20% and 0/-30% bands, four case sizes, the trim window each band buys, and real part numbers.
Wide Terminal Power Resistors: 1225, 1020 and 0612 Compared
Walsin wide terminal chip resistors: 1,708 parts at 1225, 1,708 at 0612, 878 at 1020. Real part numbers, power by size, and the TCR 1020 cannot give.
High Voltage Chip Resistors and the Limit Nobody Checks
Walsin chip resistor RCWV is the lower of root PR and a case-size ceiling. 1,136 of 4,016 general purpose parts are voltage-limited, not power-limited.
Feed-Through and 3-Terminal MLCC for EMI Suppression: How to Use the Walsin FT Series
Walsin’s FT 3-terminal feed-through MLCC is 8 parts, one 0402 and seven 0805, with no 3-pad land pattern published. How to specify one safely.
