0201 SMD Chip Resistors, 0R Links & Assortments
0201 SMD resistors for ultra-compact PCB layouts
This collection focuses on 0201 imperial chip resistors for space-constrained electronics, dense modules and fine-pitch PCB assembly. Core options include single-value 1% resistors, 0R links, multi-value assortments and bulk quantities. Because 0201 components are extremely small, footprint verification, placement capability and product-level electrical data are especially important.
What does 0201 mean?
0201 imperial describes a nominal body around 0.02 × 0.01 inches and commonly corresponds to 0603 metric. It must not be confused with 0201 metric, which is substantially smaller. The package code describes dimensions only; it does not prove resistance, power, voltage, TCR, tolerance or material technology.
Products represented
- Single-value chip resistors: selected values from 0R through ohm, kilohm and megohm ranges.
- 0R links: miniature routing or configuration jumpers with finite resistance and current limits.
- Assortment kits: mixed-value books and boxes, some combining several package sizes.
- Bulk quantities: larger packs for automated placement and repeated production.
How to select 0201 resistors
- Confirm the size system: verify 0201 imperial / 0603 metric dimensions and the recommended land pattern.
- Select resistance: check the variant notation; 4R7 means 4.7Ω, 2K2 means 2.2kΩ and 1M means 1MΩ.
- Choose tolerance and TCR: these are independent specifications and must match the circuit error budget.
- Check power and voltage: calculate dissipation, apply thermal derating and confirm maximum working voltage.
- Review pulse loading: miniature size does not establish surge or overload capability.
- Plan assembly: confirm stencil, paste, pick-and-place accuracy, inspection and rework capability for the tiny body.
- Verify packaging: distinguish single values, mixed kits, package-size choices and total piece counts.
0201 versus 0402
0201 uses less board area than 0402 but is harder to handle, inspect and rework. It generally has tighter thermal and voltage constraints, although exact limits depend on the component family. The two sizes are not footprint-compatible.
Power-rating boundary
Several 0201 listings state 1/20W, but this must not be treated as a universal collection rating. Confirm power, derating, working voltage and pulse capability for the exact part and resistance. Package size alone is not an electrical rating.
Mixed-product boundaries
Some listings contain 0402, 0603, 0805, 1206 or other size options. Only variants explicitly marked 0201 imperial should be treated as 0201 resistors. The collection also includes boundary products such as a 2010 resistor assortment, larger leaded or MELF-style resistors, an NTC thermistor and ferrite beads. NTC devices vary resistance with temperature, while ferrite beads are noise-suppression components whose ohmic-looking labels may indicate impedance rather than DC resistance. Their specifications cannot be applied to fixed 0201 resistors.
Ordering checklist

- Resistance value and notation
- Tolerance and TCR
- Power, voltage and thermal derating
- Pulse or surge requirements
- Assembly and inspection capability
- Single value, assortment or bulk quantity
- Exact package selected in mixed listings
Frequently asked questions
Is 0201 imperial the same as 0201 metric?
No. 0201 imperial commonly corresponds to 0603 metric; 0201 metric is much smaller.
Are all 0201 resistors rated at 1/20W?
No. That claim appears on specific listings only. Verify the exact component rating and derating conditions.
Can 0201 replace 0402?
No. Their dimensions and PCB land patterns differ, and electrical ratings must also be checked.
Is a 0R 0201 resistor a perfect short?
No. It has finite resistance plus current, power and voltage limits.
Are ferrite beads interchangeable with resistors?
No. Ferrite beads are frequency-dependent suppression components, not fixed resistors.
Do all assortment kits contain only 0201 parts?
No. Some combine multiple package sizes or unrelated boundary products; check the selected variant.
