Product Overview and Selection Scope
NB614S224N-TR is a polarized, ultra-thin S-type coin supercapacitor rated at 3.3 V with 0.22 F nominal capacitance. Its two short flat terminals extend from one side of the package for compact PCB mounting and tape-and-reel handling.
This device is polarized and its terminal voltage falls during discharge. Verify the ESR step, capacitance tolerance, load profile, leakage, charging current and minimum system voltage in the complete circuit.

Capacitance and ESR Test Methods
For capacitance measurement, charge the device to rated voltage for 30 minutes and discharge it at the prescribed constant current. ESR is measured using the specified 1 kHz AC method.
Hold-Up, Leakage and Energy Calculations
Estimate the usable interval from the allowable voltage window and load current, then subtract the immediate ESR voltage step. For the specified leakage-current checkpoint, apply the 3.3 V rated voltage for 30 minutes and verify a maximum of 150 µA.
PCB Mounting, Soldering and Handling
Assembly and environmental conditions directly affect reliability. Apply the following source-specification precautions during layout and process qualification.
If devices are connected in series, implement voltage balancing and obtain NYFEA application guidance. Also validate hole size, lead pitch, cleaning chemistry, polarity inspection and mechanical support before release.
Application Guidance and Design Limitations
The applications below are engineering use cases consistent with a 3.3 V rated, 0.22 F backup component. They are not end-product certification claims.
RTC BackupMaintain timekeeping through a loss of the main supply after hold-up validation.
Memory RetentionSupport low-power state preservation and orderly data save.
Smart Meter Data SaveProvide a controlled window for nonvolatile recording after mains loss.
Industrial Control Hold-UpBridge short interruptions after validating load current and ESR drop.
Wireless Sensor BackupMaintain low-power state between supply events after circuit validation.The source specification does not claim automotive, medical, functional-safety, life-support or fault-tolerant qualification. Confirm all mandatory standards for the end product.
NB614S224N-TR Engineering FAQs
What are the rated voltage and nominal capacitance?
The rated operating voltage is 3.3 V and the nominal capacitance is 0.22 F. No separate surge voltage is stated.
What capacitance tolerance is specified?
The supplied specification states −20% to +80%, corresponding to an initial range of 0.176 F to 0.396 F before additional temperature and ageing allowances.
What is the maximum ESR?
The maximum ESR is 200 Ω at 1 kHz and 10 mA at room temperature.
What is the operating temperature range?
The specified operating range is −10 °C to +60 °C.
What are the package dimensions and terminal arrangement?
The source drawing specifies a 6.66 +0.04/0 mm body diameter and 1.7 ±0.2 mm thickness. Two polarized S-type surface-mount terminal sheets are attached to opposite package faces and extend in the same radial direction; use the controlled drawing for the complete footprint.
Is the component polarized?
Yes. Match the negative marking to the PCB polarity before soldering.
Can it be used as a direct battery replacement?
No. A supercapacitor has continuous voltage decay and an ESR-related voltage step. Validate the load current, minimum system voltage, usable energy and required hold-up time.
Is a separate surge voltage specified?
No. The supplied specification states a 3.3 V rated operating voltage but does not list a separate surge-voltage value.
Which document controls production decisions?
The supplied NB614S224N-TR PDF and the current NYFEA-controlled revision remain the design authority.
This page summarizes the supplied NB614S224N-TR product specification for component evaluation. Confirm the current revision, dimensions, polarity, rated voltage, test conditions, assembly process and qualification requirements before production release.
