Capacitors & Resistors Sourcing — Passives in Production Volumes
Solluna sources capacitors and resistors through fixed partner factories — MLCCs, electrolytic capacitors, film capacitors, and chip resistors in production volumes.
Capacitors & Resistors, Explained Simply
Capacitors and resistors are passive electronic components. Capacitors store and release electrical energy; resistors limit or regulate current flow. Both are mounted onto a PCB during PCBA and are typically listed in the BOM.
Capacitors come in several types — MLCCs (multilayer ceramic), electrolytic, and film — while resistors are commonly chip resistors (SMD) or through-hole types. Solluna sources all of these through our fixed partner factories, in the quantities your production run requires.
Solluna's Capacitor & Resistor Sourcing Services
Sourcing runs through our fixed partner factories — Solluna manages the process on your side.
MLCC & Electrolytic Capacitors
Multilayer ceramic and electrolytic capacitors sourced to your capacitance, voltage, and package requirements.
Chip & Through-Hole Resistors
Chip resistors (SMD) and through-hole resistors sourced to resistance value, tolerance, and power rating.
BOM Review & Alternates
Passive part numbers reviewed before sourcing — alternates and lifecycle status checked so procurement doesn't stall.
Consolidated with PCBA
Passives are sourced in reel, tube, or bulk quantities and consolidated with other components into the PCBA run.
Passive Sourcing Connected to Production
Your passives order doesn't sit in isolation — it connects directly to the PCBA run and the BOM behind it.
Fixed Partner Factories
Capacitors and resistors are sourced through established, fixed partner factories in China, Vietnam and Southeast Asia — not one-off trading channels.
Volume Availability Check
Availability is checked before sourcing — so volume shortages or long lead times on specific values are caught before they affect production.
One Team from Design to Delivery
Design, production, and procurement sit under one Solluna team — passives are consolidated into the PCBA run without re-briefing.
