0402CG330J500NT 概要
A multilayer ceramic capacitor is a passive component that stores charge in a ceramic dielectric between alternating metal electrode layers. Within the capacitor hierarchy, MLCCs sit in the broad family of fixed capacitors, and the C0G dielectric class defines the most stable subgroup: it exhibits essentially no capacitance change with temperature (0 +/- 30 ppm/C), negligible aging, and low dielectric loss, unlike Class II X7R or X5R parts that trade stability for higher volumetric density.
Key features of this part include the tight ±5% tolerance for predictable timing and filter behavior, the ultra-stable C0G dielectric suitable for resonant and RF circuits, a 50 V rating compatible with most low-voltage digital and analog rails, and operation up to 125 C per the FindIC-listed specification line (Cap Ceramic 33pF 50V C0G 5% SMD 0402 125C, paper Tape & Reel packaging).
Because C0G ceramics have near-zero voltage coefficient and very low ESR, this 33 pF value is typically used for crystal load capacitance, RF matching networks, high-frequency filtering, and precision timing where capacitance drift would shift circuit behavior. The 33 pF value is especially common as the load capacitor pair for 32.768 kHz crystals and MHz-range quartz resonators.
Typical applications include crystal oscillator circuits in microcontroller systems, RF front-end matching in wireless modules, precision analog filters in instrumentation, and high-speed digital decoupling where stable low-value bypass capacitance is required.
Design consideration: for crystal load applications, remember that each capacitor contributes C_stray plus C_load/2 - factor in PCB parasitics (typically 2-5 pF) when selecting between 33 pF and neighboring values.

主な用途
0402CG330J500NT の用途: 6 件s: Crystal Load Capacitors, RF Matching and Filtering, Precision Analog Filters, High-Frequency Digital Decoupling, Consumer Electronics Signal Coupling, IoT and Wearable Sensor Nodes.
Crystal Load Capacitors
The 0402CG330J500NT is a canonical choice for crystal oscillator load capacitance in microcontroller and RTC designs. Its C0G dielectric provides a 0 ±30 ppm/C temperature coefficient, so the crystal's load capacitance - and therefore oscillation frequency - remains stable across -55C to +125C, which directly protects frequency accuracy in real-time-clock applications. In a typical Pierce oscillator, two capacitors of equal value connect each crystal terminal to ground; with 33 pF parts and 2-5 pF of PCB stray capacitance per terminal, the effective CL lands near the 12-20 pF range common for quartz resonators. Unlike X7R alternatives, the C0G dielectric introduces no microphonic or piezoelectric noise into the oscillator loop. Place both capacitors close to the crystal with short, symmetric traces to minimize stray asymmetry and frequency pulling.
おすすめ
RF Matching and Filtering
In RF front ends, the 0402CG330J500NT serves as a matching-network element, DC block, or high-pass filter capacitor for sub-GHz to low-GHz designs. The C0G (NP0) dielectric offers low dielectric loss and negligible capacitance change under RF voltage swing, which keeps the matching point stable and insertion loss predictable - critical for antenna matching, SAW-filter interstage coupling, and Bluetooth, Zigbee, or sub-GHz radio modules. The 33 pF value presents roughly 96 ohms of impedance at 50 MHz and under 3 ohms at 1.6 GHz, making it effective as a coupling or bypass element across common ISM bands. The compact 0402 footprint minimizes parasitic inductance (roughly 0.4-0.6 nH), preserving self-resonant frequency well above most operating bands. Use verified land patterns and keep traces at 50 ohm controlled impedance where possible.
おすすめ
Precision Analog Filters
Active and passive analog filters demand capacitors whose value does not drift with temperature, DC bias, or age - exactly the profile of the C0G-dielectric 0402CG330J500NT. In Sallen-Key low-pass topologies, RC anti-alias filters ahead of ADCs, and integrator designs in instrumentation, a 33 pF C0G capacitor sets filter corner frequencies with essentially no capacitance variation, so gain and phase margins computed in simulation hold in production. The ±5% tolerance bounds worst-case corner-frequency spread to about ±5%, versus tens of percent for Class II dielectrics under bias. The 50 V rating comfortably exceeds typical analog rail levels of 3.3 V to 15 V, and the small 0402 size lets designers place the capacitor directly at the op-amp input pin to minimize node parasitics. Pair with 1% thin-film resistors for tightly specified frequency response.
おすすめ
High-Frequency Digital Decoupling
While bulk decoupling relies on larger capacitors, small C0G parts like the 0402CG330J500NT excel as high-frequency bypass elements for clock lines, high-speed IC supply pins, and VCO/PLL supplies. The 33 pF value has low ESR and a self-resonant frequency in the hundreds of megahertz range given the 0402 package's low parasitic inductance, so it shunts fast switching transients that larger X7R capacitors cannot reach due to their own ESL. Because the capacitance does not derate under DC bias - unlike X7R, which can lose most of its small-value capacitance at rated voltage - the bypass impedance stays predictable on 3.3 V and 5 V rails. Placing one 33 pF C0G directly at a clock-generator or transceiver supply pin, alongside bulk 1 uF and 10 uF ceramics, creates a low-impedance supply network across decades of frequency.
おすすめ
Consumer Electronics Signal Coupling
In consumer audio, TV, and set-top-box boards, the 0402CG330J500NT works as a DC-blocking coupling capacitor in audio signal paths and as a snubber/bypass in tuner and IF sections. The C0G dielectric is linear and non-piezoelectric, so unlike Class II MLCCs it does not inject microphonic noise into audio lines - a known audibility issue when X7R capacitors carry signal. The 33 pF value suits high-impedance coupling nodes and compensation networks in op-amp-based preamps, while the 50 V rating covers line-level and headphone circuits with margin. Its tiny 0402 footprint supports the dense layouts typical of consumer PCBs, and the paper Tape & Reel packaging runs cleanly on high-speed SMT pick-and-place lines at volumes in the millions of placements. RoHS compliance keeps the part aligned with global consumer product regulations.
おすすめ
IoT and Wearable Sensor Nodes
Battery-powered IoT and wearable devices benefit from the 0402CG330J500NT in two roles: crystal load capacitance for the low-power RTC that schedules sensor wake-ups, and stable timing elements in RC oscillators that determine duty-cycled sampling intervals. Because C0G capacitance does not drift or age, the RTC frequency error stays within crystal tolerance over the product's lifetime, preserving timestamp accuracy without periodic recalibration. The tiny 1005-metric footprint and low profile suit tightly packed wearable PCBs, and the 50 V rating far exceeds single-cell Li-ion or coin-cell rails, providing robustness against transients. The negligible dissipation factor of C0G adds no measurable quiescent loss to the power budget. At $0.0036 per unit and with nearly a million units in stock at LCSC, BOM cost and supply risk are effectively negligible.

主な差別化要因
- Massive verified stock with lowest-friction sourcing （vs GMC04CG330J50NT)

設計ノート
Use the standard 0402 (1005 metric) land pattern of approximately 0.53 mm x 0.49 mm pads with 0.46 mm gap; excessive pad size increases stray capacitance, which matters directly for crystal load applications where each pad adds 1-2 pF. For crystal circuits, route the two load-capacitor traces symmetrically and keep them shorter than 3 mm from the crystal terminals to minimize asymmetry-induced frequency pulling. Reflow soldering per standard SAC305 profiles is fully compatible with the Ni-barrier, Sn-plated terminations.
Do not substitute an X7R or Y5V dielectric part for this C0G capacitor without analysis: Class II dielectrics derate significantly under DC bias and vary ±15% or more over temperature, which will shift crystal load capacitance and filter corner frequencies. Also verify that any substitute maintains the ±5% (J) tolerance - some 0402 C0G parts are offered at ±0.25 pF or ±10%, changing worst-case circuit spread. The hotenda listing misdescribes this passive as a microcontroller; treat the capacitor datasheet from Fenghua/LCSC as authoritative.
The 50 V DC rating applies at 125C per the Fenghua low-voltage series specification; derating to 50% of rated voltage (25 V) is a common reliability guideline for high-reliability designs, and this part comfortably supports 12 V and 24 V rails under that rule. For crystal load use on 1.8 V to 3.3 V rails, voltage stress is negligible and lifetime is effectively unlimited - Class I C0G dielectric has no wear-out mechanism comparable to electrolytic capacitors.
